It's never a good day when the electricity blows at work. It's worse when your magic power is the cause of the outage. And Tristan Clearwater is having a series of very bad days indeed. His long dormant magic is suddenly so turbulent, he has no choice but to seek out an ancient book he'd overheard his father mention once long ago, The Whispersong Lexicon.

To aid his search, he hires the dangerously handsome vampire Sebastian, who makes his unliving as a rare book dealer. However, a demonic cult disguised as a multinational conglomerate soon takes an interest in Tristan and sends Ash Hartley to lure him into their clutches. When Tristan and Ash meet, literal sparks fly as Tristan's power is amplified far beyond what he's experienced in the past. As for Ash, his world is turned on its head as he begins to question everything he believes in.

His boss, a powerful witch named Xavier Braeburn, however, questions nothing. The orders from his demonic master are clear: recruit Tristan Clearwater or kill him, all the while continuing the master plan.

While Sebastian searches for the book, Tristan undergoes training to master his power, and Ash takes on a precarious position trying to play both sides. Then, Tristan uncovers affecting the lives of thousands of people in the city.

Will Tristan be able to gain enough control to face Xavier and save the city in time? Or will the witch get his way?
